Note - I don't mean "analemna"...an analemna is a single example of a technique for what I'm talking about. I wouldn't say that the Veterans' Memorial strictly uses an analemna, except to the extent that the projection is a particular point on the analemna. In the absence of a better term, I guess I would settle on "analemnic projection", but Google comes up with zero point zero results for that.
Anyhow, whatever what kind of art this is, I really dig it, so I'd like to know if there's a term for it. Surely some Fine Arts post-doc has come up with one.
